Ripple current 0.2Arms above Impedance of capacitor effects the output ripple voltage. C3: For noise terminal Above 250V, 0.1 to 0.22µF voltage reduction capacitor Film capacitor or Ceramic capacitor Reduce the noise terminal voltage. The constant value should be evaluated in the product. R1: For noise terminal 10 to 100Ω, 1/4W voltage reduction resistor Reduce the noise terminal voltage. The constant value should be evaluated in the product. Use a rectifying diode with the peak reverse voltage of 400V or higher, the average rectification current of 1A or larger and the peak surge current of 40A or larger. When using an input capacitor of a large capacity, choose a component that endures the inrush current on power-up. This product is compatible with full-wave rectification. 120 Load Regulation Load Regulation ( Vi= −141V,Ta=25°C) -14.0 External components setting ZNR: Varistor (Vi= −141V,Ta=25°C ) 100 Vo For actual usage, Please kindly evaluate and confirm our part mounted in your product.
